Title: Centering means for resilient restraining devices
IPC: G01C19/42
Filed: 1946-06-13
Abstract: 618,456. Resilient mountings. JACK & HEINTZ PRECISION INDUSTRIES, Inc. June 13, 1946, No. 17798. Convention date, June 20, 1945. [Class 108 (iii)] [Also in Group XX] A device for resiliently constraining an object 6, Fig. 1, such as the gimbal frame of a gyroscopic device against movement about its axis 7 in either direction from a neutral position comprises a coiled spring 3 which is adjustably secured at its ends to a rigid frame 2 and is connected intermediate its ends to the object 6 by a bracket 19, means being provided for adjusting the spring lengthwise so as to centre it with respect to the pivot of the object 6. For connecting the spring 3 to the bracket 19 one or more of the convolutions of the spring are slightly elongated and threaded into a groove 16 in the bracket 19, being retained in position by a screw bolt 20. The ends of the spring 3 are clamped to the ends of the frame 2 by plates 11, 12 and screw bolts 9, 10, 13, 14; the ends of the frame 2 are tapered in thickness to minimize distortion of the spring, the end convolutions of which embrace the bolts 9 and 13. An alternative method of attaching the spring 3 to the frame 2 comprises a bracket 29, Fig. 4, having a screw-threaded shank 30 for attachment to the frame 2; one or more of the end convolutions of the spring are received in a groove 32 provided by an extension 31 on the bracket 28, being threaded on a screw bolt 33 and retained in position by spring tension only, or, if desired, by soldering. The frame 2 is mounted on a support 1 by bolts 23, 24, Fig. 3, which pass through elongated holes 25, 26 in the frame 2 and enter screw-threaded holes in a clamping plate 22. In order to provide for adjustment of the position of the frame 1 and thereby centre the spring 3, a screw 28 is rotatably mounted in the support 1 and engages a screw-threaded hole in the frame 2.
Patent GB-178112-A (GB)
Abstract: 178,112. Jaubert, G. F. April 4, 1921, [Convention, date]. Rime, thawing and removing.- In apparatus for producing liquefied air, the air is passed through two heat-exchangers A, to which the refrigerating-medium is supplied alternately from a pipe G through valves L, I, the air being directed by a four-way or other valve O first through the exchanger that is to be thawed, and then through the active cooler. The rime is collected as liquid in a vessel D and run off by a tap E. If desired the air may be passed through a drying-chamber F, containing calcium chloride or other agent, located between the exchangers. A part of the liquefied air, or one of its constituents, such as nitrogen, oxygen or argon, is used as the refrigerating-medium. Reference has been directed by the Comptroller to Specifications 2387/85, 27408/04, 865/05, and 21635/08.

Title: Preparation of equilenin sulphate and its salts
IPC: C07J75/00
Filed: 1949-07-06
Abstract: Equilenin sulphate, or its salts are obtained by subjecting equilenin to the action of chlorosulphonic acid or pyridine sulphur trioxide in the presence of an inert solvent, e.g. dry pyridine and chloroform, thereby to convert the free hydroxyl group into the corresponding 3-monosulphate.  The equilenin sulphate may be obtained in the form of a salt by neutralization of the 3-monosulphate with a base, e.g. quinidine or alcoholic potassium hydroxide.  Detailed examples are given.

Title: Process of cementing materials together
IPC: C09J105/08
Filed: 1935-06-21
Abstract: Materials are cemented together by applying a coating of deacetylated chitin, or a salt thereof such as the formate, acetate or maleate, to the surfaces to be joined, contacting the coated surfaces and drying the assembly.  The deacetylated chitin may be prepared as described in Specification 458,839, [Group IV].

The following materials may be cemented; regenerated cellulose, paper, wood, cloth, canvas, leather, glass, cork, rubber, porcelain, plaster, cement, asbestos, mica and lacquered or painted surfaces.  The adhesive is rendered insoluble by heating, by exposure to ammonia gas or by treatment with alkaline solutions, aldehydes, e.g. formaldehyde, anhydrides or acid halides. Formaldehyde, wetting agents such as hymolal salts or mould inhibitors such as phenol, thymol, and hexyl-resorcinol may be added to the adhesive solutions.  More than one coating of the deacetylated chitin may be applied and a coating of deacetylated chitin may be followed by a coating of sodium silicate solution.  The process may be used in the manufacture of safety glass, plywood, laminated paper, wood veneer paper and furniture.

Abstract: 473,712. Feeding webs. VOMAGBETRIEBS-AKT.-GES. July 2, 1936, No. 18326. Convention date, July 2, 1935. [Class 100 (i)] In a web-renewing apparatus for a rotary printing-machine fed with a preprinted web having spaced perforations or control marks, the running web passes between a pair of electric contacts 8, 10 which close a circuit at the passage of each mark, and a second circuit is closed by contacts 14, 15, when a perforation or mark on the rotating replacement roll 3 passes the brush 13 or other device provided for joining the webs together. The length of the web from the brush to the contacts 8, 10 is equal to or a multiple of the distance between adjacent marks. The circuits may light or extinguish signal lamps to indicate to the operator the correct moment for actuating the brush, or they may be in series and cause the operation of the brush automatically. The replacement roll 3 is driven at the speed of the running web by a belt 5, the pulley 7 of which is driven through a differential gear adjustable by a hand wheel so that the perforations of the two webs can be brought into register.

A screen-grid valve video or audio amplifier includes a rectifier 19 whereby the minimum value of the anode potential is limited to the D.C. potential of the screen. The screen potential is derived over series resistance 13, a shunt condenser 14 rendering the time - constant long so that the limiting level is determined by the signal level averaged over a period. The values of screen and anode resistance, 13, 12, respectively, are in such a ratio that the level at which the output is limited is approximately equal to the peak signal amplitude. Modified characteristics may be obtained by connecting a further resistance, Fig. 2 (not shown), between earth and one or other terminal of the rectifier.

Abstract: 1505585 Transistor amplifier SONY CORP 2 May 1975 [10 May 1974] 18510/75 Heading H3T A sensing circuit comprises a bipolar transistor 10 with emitter E, base B and collector C regions, the emitter carrying an insulated IGFET type gate G, the characteristic of collector current I C  against gate-emitter voltage V GE  showing a symmetrical valley about some fixed point, with bias supplies for emitter, base and gate, and a sensing device connected to the base or gate. The sensing device 11, e.g. with resistance dependent on temperature, magnetic field or light intensity, connected in a bridge to gate or base (Fig. 7 not shown) modifies the gate-emitter potential by virtue of the drop across emitter load 14. Consequent collector current variation up the steep side of the valley of the I C  versus V GE  characteristic gives sensitive output 15 across load 13, adjusted by bias control 8, which may be interchanged with device 11. The transistor may be of opposite conductivity type: the emitter and collector regions may have comparable impurity concentrations, the emitter having a further sub-region of higher impurity concentration within less than the minority carrier diffusion distance from the emitter-base junction.
